Hello there, @AniB.
Thanks for visiting the Community. I can guide you in recording the 2018 or 2019 petty cash transactions so you can move forward in filing your 2019 return.
First off, we'll need to set up a petty cash account. Then, enter all your petty cash transactions manually. Here's how:
- In the Settings menu, select Chart of Accounts.
- Select New.
- In the Account Type drop-down list, choose Bank.
- From the Detail Type drop-down list, select Cash on hand.
- Enter Petty Cash for the account name. If you have funds to use for petty cash, enter the amount in the Balance field, then choose the as of date. Otherwise, leave it blank as the opening balance will then be created when you transfer funds from the checking account.
- Select Save and Close.
There are two ways to record transactions in QBO depending on how you took the funds out.
If you wrote a check for cash, here's how:
- Select + New menu, then select Check.
- Pick Petty Cash as the payee. Select +Add new in case petty cash isn't in the payee list.
- Select Bank Account in the drop-down list.
- Furnish all necessary information.
- Click Save and close.
If you took out the cash without writing a check:
- Click + New menu, then select Transfer.
- Select the account you use to transfer the funds in the Transfer Funds From the drop-down list.
- Select the receiving account in the Transfer Funds To drop-down list.
- Enter the transfer amount in the field.
- Click Save and close.
Pretty sure you can now proceed to filing your returns after everything is recorded. Read through this article: File your sales tax return and record tax payment in QuickBooks Online. It has a step-by-step guide in using your up-to-date QuickBooks info to fill out your tax form, and record your new tax payment after filing.
For future reference, I'm also adding a resource that can help you learn about how you can review your transaction in your account register. You can review your petty cash account in the register to check the list of all your past and current transactions.
I'm always around here if you need more help. Take care.
